Package Semaphore :

+ Add interface SemBar to expose same interface between ProgressBar & Semaphore
  + Add empty function for compatibility with SemBar
Package Progress :
  + Refactor sem function to depend of Sem interface
  + Replace interface function into interface and use Sem & SemBar interface as dependencies
Update following test

progress/progress.go
